[Amended 3-16-1981 by Ord. No. 81-01; 9-9-1981 by Ord. No. 81-05; 2-18-1985 by Ord. No 85-01; 4-15-1985 by Ord. No. 85-02; 3-3-1986 by Ord. No. 86-01; 7-7-1986 by Ord. No. 86-03; 9-5-1989 by Ord. No. 89-06; 9-16-1991 by Ord. No. 91-07]
A.
In addition to the general goals listed in the statement
of purposes and community development objectives, it is the purpose
of this article to foster the protection of critical natural resources,
such as streams, floodplains, wet soils, steep slopes, woodlands and
wildlife habitat areas, and to conserve open space areas within residential
subdivisions, as well as, where subdivisions shall be of sufficient
size, to provide commonly owned open space areas for passive and/or
active recreational use by residents of such subdivisions. By providing
for lot averaging in relatively small subdivisions and cluster development
in relatively large subdivisions, as conditional uses, paved areas
may also be reduced, resulting in a lesser increase in stormwater
runoff, as well as a reduction in subdivision improvement costs.
B.
In addition, by providing for lot averaging and cluster
development as conditional uses, it is the specific goal of the Township
to minimize the potential adverse aesthetic effects of land development
on the Township as a whole and on neighboring property owners in particular,
by encouraging the use of site planning which will limit the visual
impact of development from the vantage point of surrounding properties
and nearby public roads and minimize adverse impact on adjacent subdivisions
and properties devoted to agricultural uses.
As a conditional use in the R-A, R-1, R-2 and
E-I Zoning Districts, a property owner may be allowed to modify area
and bulk regulations, provided that the following procedures and conditions
are met:
A.
Where the gross area of the tract to be subdivided is less than 15 acres, the tract shall be eligible for development utilizing lot averaging provisions hereof only, with no common open space. Where the gross area of the tract to be subdivided is at least 15 acres but less than 30 acres, the tract (unless located in an R-A District, in which event it shall be eligible for farmside village development in accordance with § 122-16) shall be eligible for development utilizing either lot averaging provisions with no common open space or cluster development with common open space. Where the gross area of the tract to be subdivided is 30 acres or greater and the tract Is located in the R-1, R-2 or E-I Districts, the tract shall be eligible for development utilizing cluster development provisions hereof (but not lot averaging provisions) with common open space.
B.
The total number of lots for tracts utilizing lot
averaging or cluster development shall be determined by:
(1)
Subtracting the following areas or portions thereof
from the gross acreage of the tract: 100% of the area within existing
and proposed street rights-of-way, 60% of the area within an identified
floodplain area and/or within a wetland area, 50% of the area having
slopes in excess of 25%. Where two or more of such conditions overlay,
the reduction shall be based only upon the singlemost limiting factor.
[Amended 7-10-2017 by Ord. No. 17-02]
C.
The site shall be suitable for development in the
manner proposed without hazards to persons or property on or off the
site due to flooding, erosion, subsidence or slipping of the soil
or other dangers or inconvenience. Conditions of soil, groundwater
level, drainage and topography shall be compatible with the proposed
site design.
D.
Conditional use approval shall not be granted unless
planning, including layout of streets and lots and, in cluster developments,
the layout of common open space areas, shall be, in the judgment of
the Board of Supervisors, in compliance with the purposes and standards
of this article.
E.
In granting or denying a conditional use or establishing conditions on such grant, the standards set forth § 122-119, where relevant, shall be applied. The burden of establishing compliance with such standards shall be upon the applicant. In addition, the following specific design standards shall be applicable:
(1)
Parking: as required by § 122-102A(2) of this chapter.
(2)
Access and highway frontage: as required by § 122-102B(1) of this chapter.
F.
In the R-2 Zoning District, either central water supply
or central sewage disposal must be provided.

[Amended 2-7-1994 by Ord. No. 94-01]
B.
No lot of such size as to be capable of further subdivision

average lot area, unless the possibility of such further subdivision
is eliminated by a deed restriction or agreement in a form acceptable
to the Township and duly recorded in the office of the Recorder of
Deeds of Chester County.
The following minimum areas of common open space
shall be designated in a subdivision of 15 acres or more utilizing

In considering whether or not conditional use
approval of a proposed cluster development shall be granted, the Board
of Supervisors shall determine that proposed common open space is
consistent with the following criteria:
A.
"Common open space," within the meaning of this article,
shall consist of a parcel or parcels of land or an area of water or
a combination of land and water within a development site designed
and intended for the use or enjoyment of residents of the development,
not including streets and off-street parking areas.
B.
Common open space shall be land which is accessible
and in suitable condition for active or passive recreation, conservation
of environmentally sensitive areas or other recreation or natural
or visual resource conservation purposes.
C.
The common open space shall be contiguous to the development
and shall be readily accessible from adjacent streets for pedestrians
and maintenance equipment. If separated from the tract by existing
roads, safe pedestrian access must be demonstrated.
D.
Consideration shall be given to the arrangement and
location of common open space to take advantage of physical characteristics
of the site and to place common open space within easy access and
view of dwelling units, at the same time preserving environmentally
sensitive area and visual resources. Areas set aside for common open
space shall contain no structure other than a structure related to
outdoor recreational use and approved by the Township Board of Supervisors.
E.
The ownership and maintenance of common open space
shall be made subject to such agreement with the Township, and such
deed restriction duly recorded in the office of Recorder of Deeds
in Chester County as may be required by the Board of Supervisors for
the purpose of preserving the common open space for such use.
F.
The Supervisors may require a suitable portion of
the open space area to be usable and physically prepared for play
fields.
G.
Common open space areas will be suitably landscaped
either by retaining existing natural cover and wooded areas and/or
by a landscaping plan for enhancing open space areas through plantings
which are consistent with the purposes of this article and which are
designed to minimize maintenance costs.
H.
Common open space areas shall, where deemed appropriate
by the Board of Supervisors, make provision for pedestrian pathways
to be available for general public use in order to provide the potential
for interconnecting pathway systems within the Township.
I.
Ownership and maintenance of common open space areas shall be in accordance with § 122-67F(2), (3) and (5) of this chapter.
J.
The location, design and layout of common open space shall be in accordance with § 122-67F(4) of this chapter.
K.
Where there exist competing values for inclusion within
common open space areas, the following priority of values shall be
adhered to, unless specifically waived by the Board of Supervisors,
in delineating common open space areas:
